Marin Cilic won 20 titles, including the 2014 US Open and the 2016 Cincinnati Masters 1000. The Croatian is ranked 1042 in the world rankings and hasn't left the Top 50 since 2008.
Cilic had a knee operation that allowed him to play only two games in all of 2023. He opened the court with a powerful crosscourt serve that challenged Kei Nishikori and Novak Djokovic. The 35-year-old won his first Grand Slam only a decade ago at the US Open.
